"Maple Leaf Rag" written by "Scott Joplin(1868-1917)".
The music of such a style is called "Ragtime Piano" or "Honky Tonk Piano".
The original sheet of music is written with straight 4/4 beats, but it is often played in shuffle-style(Triplet).
Also Keith Emerson, Andre Previn, Toshiko Akiyoshi and many other players love this title and recording.
Emerson and Previn play straight-style, Akiyoshi plays shuffle-style
I played shuffle-style. When I took this video, the piano of my studio was out of an interval because I did not tune it. However, the sound was suitable for a honky-tonk piano.
Enjoy!
